I haven't even finished the first draft for Shell Shock yet, but I've already got the cover, which I thought I'd share with you:
As you can see from the covers, Shell Shock is a sequel to my book Seven Stones. It's unmistakable by the design, though there is no overt reference to it.
There is one more yet to come, though I have yet to come up with a name. I'll have to try real hard to have it as two words, both starting with an "S", as I have with my first two. Also, I'll try to have an "O" in the second word somewhere in the middle so my cover creator can place something inside it as she has on Seven Stones and Shell Shock.
My cover designer is the wonderful Elizabeth Mackey, by the way. You can see more of her work here:
